Had a chance to use the Blade unibar today. Very impressed so far.
Things I liked...
* super comfortable grip and non-slip. Not much effort needed to grip bar.
* Bar feels really light in your hands.
* Very clean system. Everything is very easy to adjust/reset.
* no calluses on my hands

.
Improvements..
Just one, I would like to see a raised section around the center hole like a couple other manufacters are starting to do.
